Active driver-steering recommendation (DSR)
This function indicates to the driver in critical situations a steering recommenda-
tion in order to stabilise the vehicle. The active driver-steering recommendation is
activated, for example, on the right and left vehicle side when braking sharply on
different road surfaces.
Hydraulic brake assist
The brake assist system is activated by the very quick operation of the brake ped-
al (e.g. in the event of danger). It increases the braking effect and helps to short-
en the braking distance. To achieve the shortest possible braking distance, the
brake pedal must be applied firmly and held in this position until the vehicle has
come to a complete standstill.
The ABS is activated faster and more effectively with the intervention of the
brake assist system.
The brake assist function is automatically switched off when the brake pedal is
released.
Uphill start assist
The uphill start assist makes it easier to start off on steep hills. The system holds
the brake pressure produced by the activation of the brake pedal for approx.
2 seconds after the brake pedal is released. The driver can therefore move his
foot from the brake pedal to the accelerator pedal and start off on the slope,
without having to actuate the handbrake. The brake pressure drops gradually the
more you operate the accelerator pedal. If the vehicle does not start off within 2
seconds, it starts to roll back.
The uphill start assist is active as of a 5 % slope, if the driver door is closed. It is
always active on slopes when in forward or reverse start off. When driving down-
hill, it is inactive. ÐAntilock brake system (ABS)
First read and observe the introductory information and safety warn-
ings on page 93.
ABS prevents the wheels locking when braking. Thus helping the driver to main-
tain control of the vehicle.
ä The intervention of the ABS is noticeable from the
pulsating movements of the
brake pedal which is accompanied by noises.
Do not reduce the pressure on the brake pedal during the intervention of the
ABS. The ABS deactivates if the brake pedal is released. Never interrupt the appli-
cation of the brakes during the intervention of the ABS! Ð Traction control system (TCS)
Fig. 97
TCS button
First read and observe the introductory information and safety warn-
ings on page 93.
The TCS is automatically activated after starting the engine. If the wheels are
slipping, the TCS adapts the engine speed to the conditions of the road surface.
The TCS makes it much easier to start off, accelerate and climb steep hills even if
the conditions of the road surface are unfavourable.
The TCS should normally always be switched on. It may be advisable to switch off
the system in certain exceptional circumstances, such as:
› when driving with snow chains;
› when driving in deep snow or on a very loose surface;
› when it is necessary to
“rock a vehicle free” when it has got stuck.
Ensure the TCS is switched on again afterwards.
During an intervention of the system, the TCS warning light  flashes in the in-
strument cluster.
The TCS warning light  » page 21 lights up in the instrument cluster when there
is a fault on the TCS. £

WARNING
■ During the first 500 km, new tyres do not offer optimum grip and appropri-
ate care should therefore be taken when driving - risk of accident!
■ Never drive with damaged tyres - risk of accident!
■ Only use those tyres or wheel rims which have been approved by ŠKODA for
your model of vehicle. Failure to observe this instruction will adversely affect
the road safety of your vehicle - risk of accident!
■ The maximum permissible speed for your tyres must not be exceeded under
any circumstances - risk of an accident resulting from tyre damage and loss of
control of the vehicle.
■ If the inflation pressure is too low, the tyre must perform a higher rolling re-
sistance. At higher speeds the tyre will warm up as a result of this. This can
result in tread separation and a tyre blowout. WARNING (Continued)
■ Do not, where possible, replace individual tyres but at least replace them on
both wheels of a given axle at the same time. Always fit the tyres with the
deeper tread depth to the front wheels.
■ Never use tyres if you do not know anything about the condition and age.
■ You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn down.
■ Worn tyres do not provide the necessary adhesion to the road surface at
high speeds on wet roads. One could experience
“aquaplaning” (uncontrolled
movements of the vehicle - “swimming” on a wet road surface).
■ Immediately replace damaged wheel rims or tyres.
■ Do not use summer or winter tyres that are older than 6 years or 4 years re-
spectively.
■ The wheel bolts must be clean and must turn easily. However, they must
never be treated with grease or oil.
■ If the wheel bolts are tightened to a too low tightening torque, the rim can
come loose when the car is moving - risk of accident! A tightening torque
which is too high can damage the bolts and threads and this can result in per-
manent deformation of the contact surfaces on the rim.
■ In case of incorrect treatment of the wheel bolts, the wheel can loosen
when the car is moving - risk of accident!
■ Observe the national legal regulations relating to the use of tyres and snow
chains. CAUTION
■ If a spare wheel is used that is not identical to the fitted tyres, the following
must be observed » page 173, Spare wheel.
■ The prescribed tightening torque of the wheel bolts for steel and light alloy
wheels is 120 Nm.
■ Protect the tyres from contact with oil, grease and fuel.
■ Replace any lost valve caps immediately. For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption. £

detailing the tyre size and tyre inflation pressure
First read and observe the introductory information and safety warn-
ings on page 170.
Wear indicators
The base of the tread of the tyres has 1.6 mm high wear indicators installed.
These wear indicators are located multiple times depending on the make and are
evenly spaced around the circumference of the tyre » Fig. 140 - . Markings on
the walls of the tyres through the letters

“TWI”, triangular symbols or other sym-
bols identify the position of the wear indicators.
The life of your tyres very much depends on the following points:
Tyre pressure
The working life of tyres will be shortened considerably if the tyres are insuffi-
ciently or over-inflated and this will have an adverse effect on the handling of
your vehicle. Therefore check the tyre pressure, including that of the spare wheel,
at least once a month and also before setting off on a long journey.
ä The tyre inflation pressures for
summer tyres are indicated on the inside of the
fuel filler flap » Fig. 140 - . The inflation pressures for winter tyres are 20 kPa
(0.2

bar) higher than those for summer tyres.
The tyre inflation pressure for tyres of the tyre size 205/50 R17 that are designed
to be used with snow chains, is identical to the tyre inflation pressure for tyres of
the tyre size 225/45 R17.
The tyre pressure should be at the highest pressure specified for your vehicle at
all times. The tyre inflation pressure of the spare wheel R 18 is 420 kPa.
Always check the inflation pressure when the tyres are cold. Do not reduce the
higher pressure of warm tyres. If the load varies greatly, adjust the tyre inflation
pressure accordingly.
Driving style
Fast cornering, sharp acceleration and braking increase the wear of your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influences
when driving which may result in an imbalance and which makes themselves felt
through vibration in the steering.
Have the wheels rebalanced after replacing the tyres.
Wheel alignment errors
Incorrect wheel alignment at the front and rear will not only increase wear-and-
tear on the tyres but will also has an adverse effect on vehicle safety. In the
event of any unusual tyre wear, seek assistance from a ŠKODA specialist garage.
Tyre damage
Drive over curbs on the side of the road and other such obstacles slowly and,
where possible, at a right angle in order to avoid damage to tyres and wheel
trims.
We recommend checking your tyres and wheel rims for damage (punctures, cuts,
splits and bulges, etc.) on a regular basis. Remove foreign bodies from the tyre
profile.
Unusual vibrations or pulling of the vehicle to one side could be a sign of tyre
damage. If there is any doubt that a wheel is damaged, immediately reduce your
speed and stop! Check the tyres for signs of damage (bulges, splits, etc.). If no ex-
ternal damage is evident, drive slowly and carefully to the nearest ŠKODA special-
ist garage to have the vehicle checked. Ð

Wheels and Tyres

Tyre control display
Fig. 145
Button for setting the tyre infla-
tion pressure control value
First read and observe the introductory information and safety warn-
ings on page 170.
The tyre control display compares the speed and thus the rolling circumference of
the individual wheels with the help of the ABS sensors. If the rolling circumfer-
ence of a wheel is changed, the warning light
 in the instrument clus-
ter » page 24, Tyre control display  and an audible signal sounds.
The rolling circumference of the tyre can change if: › the tyre inflation pressure is too low;
› the structure of the tyre is damaged;
› the vehicle is loaded on one side;
› the wheels of an axle are loaded heavily (e.g. when towing a trailer or when
driving uphill or downhill);
› snow chains are mounted;
› the temporary spare wheel is mounted;
› one wheel per axle was changed.
Basic setting of the system
After changing the tyre inflation pressure, after changing one or several wheels,
the position of a wheel on the vehicle (e.g. exchanging the wheels between the
axles) or when the warning light lights up while driving, a basic setting of the sys-
tem must be carried out as follows:
› Inflate all of the tyres to the specified inflation pressure
» page 171, Service life
of tyres .
› Switch on the ignition.
ä
›
Press and hold the button

  » Fig. 145 for longer than 2
seconds. While
pressing the button, the warning light  illuminates. At the same time the sys-
tem memory is erased and the new calibration is started, which is confirmed
with an audible signal and then the warning light  goes out.
› If the warning light
 does not go out after the basic setting, this indicates a
system fault. Seek help from a ŠKODA specialist garage.
The warning light  is lit
If the tyre inflation pressure of at least one wheel is insufficiently inflated in com-
parison to the stored basic value, the warning light  » lights up.
The warning light  flashes
If the warning light flashes, there is a system fault. Seek help from a

ŠKODA spe-
cialist garage to correct the fault. WARNING
■ When the warning light  illuminates, immediately reduce the speed and
avoid sudden steering and brake manoeuvres. Stop the vehicle as soon as
possible and inspect the tyres and their inflation pressure.
■ Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light  can be delayed or does not light up at all.
■ The tyre control display does not absolve the driver of the responsibility to
ensure the correct tyre inflation pressure. For this reason, the tyre inflation
pressure must be checked regularly. Note
■ The tyre control display does therefore not replace the regular tyre inflation
pressure control, as the system cannot detect an even loss of pressure. ■ The tyre control display cannot provide a warning in the event of very rapid tyre
inflation pressure loss, e.g. in the case of sudden tyre damage. In this case care-
fully bring the vehicle to a standstill without sudden steering movements or
sharp braking.
■ To ensure a proper functioning of the tyre control display, it is necessary to re-
peat the basic setting every 10 000 km or once a year. Ð

Wheels and Tyres

Wheel bolts
First read and observe the introductory information and safety warn-
ings on page 170.
Wheels and
wheel bolts are matched to each other in terms of design. Each time
you fit other wheels, e.g. light alloy wheels or wheels with winter tyres, you must
therefore also use the matching wheel bolts of the correct length and shape of
spherical cap. This is essential to ensure that the wheels are tightly fitted and
that the brake system operates properly. ÐWinter tyres
First read and observe the introductory information and safety warn-
ings on page 170.
The handling of your vehicle will be significantly improved when driving on wintry
roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow
and at temperatures below 7 °C because of their construction (width, rubber
blend, tread pattern). This particularly applies to vehicles which are equipped with
low-profile tyres
or high-speed tyres (code index H or V on wall of tyre).
To achieve the best possible handling properties, winter tyres must be fitted on
all 4 wheels, the minimum tread depth must be 4
mm and tyres must be no older
than 4 years.
Winter tyres of a lower speed category can be used provided that the permissible
maximum speed of these tyres is not exceeded even if the possible maximum
speed of the vehicle is higher. For the sake of the environment
Fit the summer tyres on again in good time as they provide better handling prop-
erties, a shorter braking distance, less tyre noise, and reduced tyre wear on roads
which are free of snow and ice as well as at temperatures above 7

°C. The fuel
consumption is also lower. ÐSnow chains
First read and observe the introductory information and safety warn-
ings on page 170.ä
ä
ä Snow chains must only be mounted on the front wheels.
When driving on wintry roads, snow chains improve not only traction, but also the
braking performance.
For technical reasons, it is only permissible to fit snow chains with the following
wheel/tyre combinations.
Wheel size Depth (D)Tyre size
6J x 15 a)
47 mm 195/65
6.5J x 15 a)
50 mm 195/65
6J x 16 a)
50 mm 205/55
6J x 17 b)
45 mm 205/50 a)
Only fit snow chains with links and locks not larger than 15 mm.
b) Only fit snow chains with links and locks not larger than 9 mm.
Remove the full wheel trims before installing the snow chains.
Observe the national legal regulations relating to the use of snow chains and the
maximum vehicle speed with snow chains. CAUTION
The chains must be removed when driving on roads which are free of snow. They
adversely affect the handling of your vehicle, damage the tyres and are rapidly
destroyed. Ð176
